Although research on the nonverbal expression of emotion has played a prominent role throughout psychology during the past two decades—including an instrumental role in the development of contemporary evolutionary psychology—little research has focused on the evolutionary origins and functions of the emotional expressions themselves. However, recent findings from psychophysical, comparative, so...

Abstract. Using Hankel operators and shift-invariant subspaces on Hilbert space, this paper develops the theory of the operators associated with soft and hard edges of eigenvalue distributions of random matrices. Tracy and Widom introduced a projection operator W to describe the soft edge of the spectrum of the Gaussian unitary ensemble. The subspace WL is simply invariant under the translation...

The apparent molecular size and charge of immunoreactive gastrin components were studied in sera from patients with pernicious anaemia or gastrinomas (the Zollinger-Ellison syndrome) by Sephadex gel filtration and aminoethylcellulose chromatography. The following serum components were distinguished: (1) a monophasic component I similar in size to proinsulin which was converted into ;little' gas...

By using a tau construct with two mimicked acetylation sites as identified in AD brains, Tracy et al. (2016) found that acetylated tau promotes synaptic dysfunction through disruption of postsynaptic KIBRA signaling pathways, actin dynamics, and AMPA receptor trafficking.

Investigating the long time asymptotics of the totally asymmetric simple exclusion process, Sasamoto obtains rather indirectly a formula for the GOE Tracy-Widom distribution. We establish that his novel formula indeed agrees with more standard expressions.

We investigate the probability distribution of the length of the second row of a Young diagram of size N equipped with Plancherel measure. We obtain an expression for the generating function of the distribution in terms of a derivative of an associated Fredholm determinant, which can then be used to show that as N → ∞ the distribution converges to the Tracy-Widom distribution [TW] for the secon...
